如果刚入门,首先推荐汤姆爱弗瑞的网球教学片,讲基本动作和纠正,是比较基础的;
如果这个觉得太浅,就《尼克网球教程》,教父级的指导。
如果还觉得浅,那就央视5运动空间那套系列片,这片子涉及一些战术运用了。
汤姆网球教程-1,基本技术
-lesson 1, grip
为了击球是球拍垂直,半西方,西方最容易。
-lession 2, backswing is crucial for consistency 引拍是稳定的关键。
拍面略微关闭。击球时从下向上,保证垂直击球。
-lession 3, why the balls go in the net? how to correct it? 解决下网问题。
200 mile/h 才能使得平击球过网。所以要从下向上。 降低重心 曲膝。
小臂动了, 球就没了。
用手腕和小臂打球是头号杀手。
击球时球拍降低一尺,肩膀到下巴 (每个动作1-2要领) 拍面向下,起来。 垂直接触球。
-lession 4, why the ball goes long. 拍面太开
-lession 5, 保持垂直拍面的练习。 对着网或墙,挥拍
-lession 6, 截击, 下网原因: 没侧身, 没动脚。 目标网上1-1.5米位置。 左手托拍(帮助转身)。向前击球。
-lession 7, serve. in the net. 向上击球,抬头挺胸。 向上刷7点到1点。 瞄准底线。
-lession 8, serve goes long. 抛球向后。
-lession 9, overhead goes in the net. 头过早低下。 抬头挺胸, 向前击球。可能2, 低估网的高度。抬头挺胸,多等一下
-lession 10,
===================================
汤姆网球教程- 2,单双打战术
网中间91公分,两边102.
-lession 2, 截击技术
-双打抢网: 45度向前抢网。
肘关节远离身体。
反手切削只能打开5-10度。
=======================================
汤姆网球教程- 3, 发球
侧旋球水平方向, 削的薄,有人甚至打到框上。
上旋 7-1点, 练习: 左手手掌托球,右手持牌撮球。
伸直手臂, 多等一下 (抛球手)
350-001 Routing & Switching
.
Day 1, May 23,
.
Q1, In order to maintain security, with which hop count are IPv6 neighbor discovery packets sent?
[A]A suggestion (RFC 3682) of using a "hop count of 255" has only rather limited value.
Q2, Which command will define a VRF with name 'CCIE' in IPv6?
[A] vrf definition CCIE
Q3, LDP advertise which route?
[A] IGP
Q4, Which command can be used on a PE router to connect to a CE router (11.1.1.4) in VRF red?
[A] telnet 11.1.1.4 /vrf red
Q5, The routing inside the VPN RED will work without any special OSPF configuration
Q6, Which two statements are correct about Nonstop Forwarding? (Choose two.)
[A] B. It is a Layer 3 function that works with SSO to minimize the amount of time a network is unavailable to users following a switchover
E. The main objective of NSF is to continue forwarding IP packets following a switchover
SSO=> stateful switchover
Q7, Which three fields are optional in an OSPFv3 external LSA? (Choose three.)
[A] A. Forwarding Address
B. External Route
C. Reference Link-State ID
Q8, On a router, interface S0 is running EIGRPv6, and interface S1 is running OSPFv3. A redistribution command is issued under OSPFv3, redistribute EIGRP 1 metric 20 under ipv6 router nospf 1. What will happen after applying this redistribution command?
[A] All routes showing up as D and D EX in the routing table will be redistributed into OSPFv3.
Q9, Which type of domains is interconnected using Multicast Source Discovery Protocol?
[A] PIM-SM
Q10, Which two multicast address ranges are assigned as source-specific multicast destination addresses and are reserved for use by source-specific applications and protocols? (Choose two.)
[A] 232.0.0.0/8 and FF3x::/32
Q11, How is RPF used in multicast routing?
[A] to prevent multicast packets from looping and to instruct PIM where to send a (*,G) or (S,G) join message
Q12, What does the incoming interface of the above (*,G) entry indicate?
[A] the interface closest to the RP, according to the unicast routing table
Q13, Which interface(s) will show ip rpf 1.1.1.2 indicate as RPF interface(s)
[A] ethernet 1/0
Q14, Apart from interdomain multicast routing, what else is MSDP used for?
[A] anycast RP
Q15, Which IGMPv2 message contains a non-zero "Max Response Time"?
A. Membership Query
Q16, Which IGMPv2 message is displayed in the output of the packet capture?
B. Membership Report
Q17, What is Phantom RP used for?
B. it is used for redundancy in bidirectional PIM
Q18, Which three statements are true about TACACS+? (Choose three.)
A. It is a Cisco proprietary protocol.
C. Authentication and authorization are done at different stages.
D. TACACS+ encrypts the entire body of the packet, but leaves a standard TACACS+ header.
Q19, Which two statements are correct? (Choose two.)
B. The access list has logging enabled.
D. The command ip access-list logging hash-generation is enabled
Q20, C. NTP is not configured on the router.
Q21, What does Cisco recommend when you are enabling Cisco IOS IPS?
A. Do not enable all the signatures at the same time
Q22, B. OSPF peers are using Type 2 authentication. (MD auth)
Q23, Which two statements are true about Unicast Reverse Path Forwarding Loose Mode? (Choose two.)
A. It is used in multihome network scenarios.
B. It can be used with BGP to mitigate DoS and DDoS.
Q24, ##aaa authentication login default group tacacs+ none.
